Nvidia patents method to simulate quantum circuits on standard computers
Nvidia describes a way to simulate quantum computers using regular hardware by breaking the complex quantum state into smaller, manageable pieces. The system tests different ways to split this data and picks the option that uses memory most efficiently for the specific computer running the simulation.
In the filing’s own words
In various examples, systems and methods for simulating quantum circuits using sparse state partitioning are provided. The quantum state of a quantum circuit may be partitioned into one or more state vector partition candidates that may form sparse state partitions that avoid memory operations for one or more state elements of the quantum circuit's state vector. Gate grouping, gate complexity, and/or qubit ordering optimization algorithms may be applied and the state vector partition candidate evaluated against a computing platform topology profile using a cost evaluation function. The cost evaluation function may estimate an efficiency associated with executing that state vector partition candidate given the processing resources of the currently available simulation platform for running the simulation. A state vector partition candidate optimized for the simulation platform may be passed to the simulation platform as a set of state vector partitions in order to simulate the quantum circuit.
What exactly they claim (claim 1)
1. A processor comprising: one or more circuits to: generate, based at least on a representation of a quantum computing circuit, at least one candidate set of state vector partitions that includes a plurality of state partitions; compute an efficiency associated with executing the at least one candidate set of state vector partitions based at least on a topology profile defining computing resources of a topology of a quantum simulation computing platform; select a subset of state vector partitions from the at least one candidate set of state vector partitions based at least on the efficiency; and simulate the quantum computing circuit on the quantum simulation computing platform using the selected subset of state vector partitions.
